Therefore, smart meter systems are required to employ a reliable multicast protocol. However, in conventional protocols, STAs are not allowed to transmit their data frames until the multicast protocol is completed. As a result, conventional protocols degrade delay performances and frame loss rates of STAs. This paper proposes a grouping method of STAs to improve delay performances and frame loss rates. The evaluation system model is based on the IEEE 802.11ah sensor network which has a large number of STAs. Computer simulation results show that delay performances and frame loss rates  are improved compared with the conventional one.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告ユビキタスコンピューティングシステム（UBI）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2013-05-09","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"25","bibliographicVolumeNumber":"2013-UBI-38"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-18T23:41:06.125041+00:00","id":92071,"links":{}}
